To all 'whom t fmaylconcern:

Be it known that L WILLIAM Scnwix'n,

e citizen of the United States, residing etV Kansas City, in the countyof Jackson and 'Ste-te of Missouri, have invented new end usefulImprovements in Feeding and Meesuring Devices, of which the following ise specification.

My present invention relates to improvements in devices for feedinglmeasured or graduated -lenzfgths or quantities ofpeper end similarmateriels and such nnprcve ments ere especially applicable to appartetus for making photographic prints upon strip or web of sensitized peperor ether vsinn-xd rfc-r prints of eecli size Witheet re quiring cere andattention )from the operzitor after the measuring Ineens has neenappropriately set.

Furtherobjects of the invention are te provide in a. measuring deviceoff this cherlinciter ineens Where-by the device may be quickly endimmediately reset Lifter each lfeeding and measuring opere-tion and 'teenable the feeding mens to he operated independently oi' the measuringmeans.

Similar parte ere designated by the seme reference characters in theseveral 'ievvs i Feeding end measuring devices constructed in nccerdencewith the present invention are cepebie of uise generally in veiiousinstances Where it ie desirable or necessary 'to feed ,measuredorgredneted lengths of peper nnd other materiels. in the presentinstance the preferred forni ci feeding and 'rneesnring device is shownend it is :ipplied to une forni ci' apparatus whereby nleesureiii orgraduated lengths of sensitized peper :ire Within tlie'e'pperetus es :ipart oi. the crecess of nnxlrini photcgrephic prints. it te heundersteod, however, that the inventiefn is net necessarily limited tothe particular construction shown, nor is its use confined necessarilyto appare-tus of the particular forni referred to.

In the present instance the photographic apparatus to which 'theinvcntinn is :applied comprises a` casing 1 which contains esupply @ifsensitized paper or material 2, this' instel-inl, lying in the focnlplane of e cerner-Liv which ornis e part of such epperzv tus, and thisstrip or )veli of material is fed to and 'from the exposing positionlim' :i pair of rollers 3, e knii'e. i being; lccied below the rollersto sever the strip of peper or mnterizil inte sections which conform insize to the .sise selected fer the prints, and these severed printsenter n, developing 'tank the feeding of the strip being effected lrotation of the rollers fi between which the paper, pas, @ne of theserollers is pre vided with e gen1' pinion' (i and this geni' pinioncoperntes with the 'feeding and measuring device which forms the subjectof the present inventien.

The 1feeding1 and measuring device as shown in the present instniicelroinpriscs e, casing con'iposcd mc n body section y7 and a removablecover or face plate 8, these sections or parts being secured together byscrews 9 Fig. 2 or other suitable means. A shaft 10 extends through abearing 11 Fig.

6 formed in the rear wall of the section 7 and bears a gear 12 whichcoperates with the gear pinion 6 o-n the feed roll 3, this gear andpinion being maintained in cooperative relation by the casing' which issecured by suitable means to the side wall of the machine. The oppositeend of the shaft 10 is surrounded by' a sleeve 13 which extends througha bearing 14 formed as a part of the.cover or face plate 8 and an 15operating crank 15 is fixed to the outer or exposed end of said sleeve.The sleeve and the crank thereon are capable of axial movementrelatively to the shaft 10, but these parts have a,4 spline connectionwith said shaft which in the present instance comprises a key 16 Fig. 2which operates in va slot 17 formed in the outer end of the shaft.

A gear pinion 18 and a toothed clutch member 19 are revolubly mounted onthe shaft 10 and are contained within the casing. The inner end of theaxially movable sleeve 13 also embodies a toothed clutch member 2O whichis complemental to and coperative with the clutch member 19.- The clutchmembers 19 and 20 are normally held in engaged relation to form adriving connection between the crank 15 and the pinion 18 by a spring 21which surrounds the sleeve 13 and bears against the outerside of theclutch member 20. A forward shifting movement of the crank 15, or amovement of this crank to the right in Fig. 6, will disengage .ne clutchmembers and thereby interrupt the operative connection between the crankand the pinion 18. Turning of the i crank 15 effects the feedingoperation of `the feed rolls 3 and to prevent retrograde `rhotion of thefeed rolls, a ratchet wheel 22 .,'Figl 9 is lpreferably formed on theclutch member 20 and a pawl 23 normally cooperates with this ratchetwheel, this pawl being pivoted to the body portion of the casing at-24Fig. 5 and a spring 25 acts upon the pawl to retain it in engagementwith the ratchet wheel.

The pinion 18 which is loose on the shaft 10 but may be operativelyconnected to this shaft by the engagement of the clutch members 19 and20 coperates with a gear 26, the latter being revolubly.-V mounted on astud shaft 27 which is secured in a boss 28 formed in the rear wall ofthe casing, and this gear is preferably formed with a drum 29 whichcontains a coil spring 30, the inner end of 50 this coil spring beingattached at 31 to the hub 32 of the gear While the outer or opposite endof this spring is attached to a pin 33 Fig. 5 which is secured in therear wall 'of the casing section 7. ,A suitable number of projections 34serve to prevent undue experision of thespring. The spring operates onthe gear 26 in a manner to produce a tendency of this gear to rotate inone direction. Rotation lof the gear 26 under the action of the spring30 is limited by a relatively xedf 70 stop 35 which is-secured to thecasing section 7 and coperates ywith a controlling projection 36 whichis secured to the gear, the controlling projection 36 on the gearnormally resting against the limiting stop 35. The degree of rotation ofthe gear 26 determines the amount or length of paper or material fed byturning of the crank 15, and according to the present invention, theangle through which the gear 26 rotates may 30 be adjusted or regulatedwhereby different lengths of paper or material may be fed. The means forlimiting rotation of the gear 26 to terminate each feeding operationems/j bodies in the present instance an arm 37 |85 the outer end ofwhich lies in the path of the controlling projection 36 on the gear, iti being understood that this controlliit'g projection can operate onlywithin thel-` limits determined by the arm 37 and the limiting 90 stop35. This arm 37 is mounted on a sleeve 38, the sleeve extending througha bearing' 39 formed as a part of the cover or face plate 8, and acrankor handle 40 is fixed to the outer end of the sleeve 38 and isadjustable 95 about the latter as an axis, rotation of the handle 40serving to set the arm 37 in diiferent vadjusted positions. -In order toretain 4theoarm 37 in different Aadjusted positions,

the cover or face .plate 8 is formed with a set of locking apertures 41which are concentric with the axis of rotation of the adj justing handleor crank 40, and this handle or crank bears a .springpressed plunger 42which is adapted to enter andcoperate with any one of the apertures 41to thereby lock the handle or crank 40 in the desired posi tion. Thisspring-pressed plunger has a knob 43 which serves not only to retractthe plunger and thereby unlock the handle or crank, but it also servesas means for mani nlating the handle or crank 40. The locking apertures41 are preferably spaced to conform to a scale of inches and fractionsthereof so that the spring-pressed plunger on the handle or crank 40 maybe engaged vin the particular aperture which corresponds to the lengthof paper to bc fed.

In operation, the handle'or crank. 40 is first set according to thelength of paper to be fed at which time the gear 26 will occupy aninitial position, that is to say, the controlling projection 36 on thisgear will abut against the stationary limiting stop The crank 15 is thenturned and as the 125 spring 21 retains the clutch members 19-and 20 inengagement, rotary motion will be transmitted from the crank 15y to theshaft 10 by reason of the spl-ine'connection be'- tWeen the crank andshaft, and the gear 12 1,053g0ee on this` shaft will cause feedingmotionof the feed rolls 3. The spring 21 normally re# tains the clutch"members 19 and 20 in engagementaniehnee, turning motion of the crank 15will alsobek transmitted to the pinion/18, and as this pinioncoperateswith the 4gear 26, the latter Will`be rotated to a degreecorresponding to thedegree of rotation imparted to the shaft 10.Thefeeding motion of the paper due to ltli.- turning. of the crank 15may continue until the gear 2G has rotated to a point Where thecontrolling projection 36 thereon abuts against the properly set arm 37and this terminates the feeding operation. ln order to reset.- thedevice after one feeding operation and preparatory to the nextoperation, it is only necessary to pull the crank 15 outwardly or towardthe right in Fig. 6, the clutch mem# bers 19 and 20 being therebydisengaged and the spring 30 Will return the gear 26 to. initialposition, the gear pinion 18 being at this time disconnected from andlooseonthe shaft 10. i

rEhe present'invention also provides means `whereby the-measuring partof the device may be temporarily rendered inoperative to enable the feedrolls to be rotated cont-inuously or Without interruption. In thepresent instance a locking device in the form of a disk 44 is employed,this disk having a slot 45 therein and the disk is adapted to beinserted between the hub of the crank 1.5 and the opposed outerrend ofthe bearing 14 While the crank 15 is Withdrawn to disconnect the clutchmembers19 and 20. While this disk or locking device is so placed, theclutch members 19 and 20 are held in disengaged relation. To prevent thedisk or locking device from dropping out of place, it is preferablyformed with recess 4:6 which is adapted to receive the inner end of thehub on the crank 15, asshoivn in 9;

The operation of a feeding and measuring device co-nstructediinaccordance with the ypresent embodiment of my invention may be brieflydescribed as follows: The arm et() to which the adjustable limiting stop37 is attached is unlocked by Withdrawal of the plunger 42 and rotationto a point where this plunger registers with that part of theindicatingscale designating theleugth of material to befed at eachoperation.. lnitial1y,'the stop 3G "on the measuring wheel will abutagainst the stationary stop 35 and the clutch members 19 and 20 will beheldin engaged relation by the spring 21. The paper or other material isfed in the present instance by rotation of the feeding member 12 on theshaft 10, such rotation being effected by the crank handle 15. As theclutch member 19 is turnedI by the clutch` member 20 when engaged,ltherewith, tlie gear or pinion 18 attached to the clutch member 19 willrotate the'measuring wheel at a rate proportionate to the operation ofthe feed member and the feed member may continue to operate to feed thematerial until the projection 36 on the measuring Wheel abuts againstthe adjustable stop 37 Where; upon further feeding operation of themeinber 12 is prevented. To repeat the feeding and measuring operation,it is only necessary tol disengage the clutch members 19 and 2O which,can be readily accomplished by moving the crank handle 15 to the right,the clutch members being thereby disengaged andfthe spring BO willautomatically restore the measuring member to initial position with theprojection 36 thereon engaging the stationary stop 35. Rengage ment ofthe clutch members after their restoring operation is accomplishedautomatically by the spring 21, and the feeding and measuring operationmay be then repeated. iBy setting the arm 1i() in different angularpositions, it is obvious that diiferent lengths. of paper or othermaterial may be readily f ,feds
